Vibration Source?

All speakers vibrate. Its how they work. Can you narrow it down a little?

I, too, have found issues with recordings. On one CD, there was a distinct low frequency 'thump'. I originally thought it to be a manufacturing defect on the CD, but when playing the same album via Qobuz, I heard the exact same 'thump' at the same time on the recording.
So, I think a distinct possibility is that the original recording may have a flaw.
Perhaps if you can try a streaming app and see if the same issue occurs, then you might have your answer.

Basically, it sounds like a buzz coming from around the speakers. My first thought was that it was some part of the living room vibrating from a resonant frequency, as frequently happens in cars. Or, maybe the midrange drivers need to be replaced in the speakers. But on closer inspection it is definitely not the former. I can't pinpoint the exact source of the buzz on the speaker, so it seems as if it coming from inside the sound field, aka the recording. I've never heard anyone talk of this issue, so I'm confused. The main thing is that it could be either side of the stereo image and always comes from one specific instrument in a recording. The buzz is faint and is imperceptible during louder passages of music (on a track where it even occurs at all.) Do I need to hire someone with "golden ears" to come by and tell me what the problem is?

Just curious if the “vibration” through the speakers is your system trying to resolve some detail on certain recordings and being unable to unveil the detail due to some system deficiency. When you said the same passage comes across as just “noise” on your car stereo that also made me think that the system is falling down, not necessarily the recording. 

I don’t know what CD player you are using or what preamp, amp or integrated amp or what interconnects you are using but my gut tells me that they could play a role. 

Can you take the noisy recording to your local brick & mortar audio dealer and ask to audition that same track on some premium gear? Then you would have some points of comparison. 

Could you you tell us what CD specifically and what tracks you are experiencing this? 

I listened to CD for many years over a highly veiled system - NAD 2200 amp, with a little portable SONY D5 CD player and I would enjoy the basic structure of my recordings but always knew that the undefined “vibration” that I heard on my favorite tracks was a lack of revolving power from my system components. Forgive me if I’m wrong here - this is mostly some speculation by me.

yes you do but you live too far away for me to visit. 

it could be your ears or just bad speakers. Most speakers are bad.
